Nutrient .NET SDK is organized in clear layers so you can build and scale document workflows without changing stacks:

  • App/UI layer — Build with WinForms, WPF, MAUI, web/WASM hosts, or backend services.
  • SDK API layer — Integrate through a consistent public API surface for document operations.
  • Document processing core — Combine capabilities such as PDF processing, imaging, OCR and data extraction, barcode reading and writing, conversion, and viewing/annotation.
  • Platform targets — Run across Windows, Linux, and macOS, with a separate WebAssembly (browser) target.

This layered approach helps teams start with standard use cases and expand into advanced processing scenarios over time.
